This is for the 35L versionVery Quiet, gets down to -20C easily in an ambient of 19CPoor instructions covering multiple models and no mention of the phone app. The app is called 'carfridgefreezer' by alpicool and it worksFor a replacement 12v DC lead do a 'Google' for "12V lead for Waeco CF40 Fridge"The voltage indication is misleading but accurate, it does accurately indicate the voltage at the fridge but not the battery voltage as it does not take into account voltage drop along the 3mtr 12V battery lead. This works to your advantage as it means that the fridge cuts out at a true battery voltage of 11.5v which saves damaging your battery. If it went down to 11V it would reduce the battery life. Although you can only set one temperature and that's for the main compartment, there is a smaller compartment above the compressor which is at a higher temperature. I've found that if I set it to -5C the main compartment remains frozen but the smaller area is ideal for chilled food and doesn't freeze.Eco mode is a waste of time, it runs the compressor slower but longer so therefore takes the same total amount of energy to maintain temperature. It may also have a detrimental effect on the compressor running it slower.For hidden menu settings do a 'Google' for "alpicool hidden settings cf35"
